An easier way to determine that the password has been
changed correctly is to read the ACK bit following the
second writing of the new password. If the device returns
an ACK, the password is good. A No ACK indicates
something went wrong. If there was an error, the pass-
word remains unchanged.
There is no way to read any of the passwords.

*COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and the functional operation of
the device at these or any other conditions above those
listed in the operational sections of this specification is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
